A unifying theory of general anesthetic-induced unconsciousness must explain the common mechanism through which various anesthetic agents produce unconsciousness. Functional-brain-imaging data obtained from 11 volunteers during general anesthesia showed specific suppression of regional thalamic and midbrain reticular formation activity across two different commonly used volatile agents. These findings are discussed in relation to findings from sleep neurophysiology and the implications of this work for consciousness research. It is hypothesized that the essential common neurophysiologic mechanism underlying anesthetic-induced unconsciousness is, as with (...) sleep-induced unconsciousness, a hyperpolarization block of thalamocortical neurons. A model of anesthetic-induced unconsciousness is introduced to explain how the plethora of effects anesthetics have on cellular functioning ultimately all converge on a single neuroanatomic/neurophysiologic system, thus providing for a unitary physiologic theory of narcosis related to consciousness.

One method for investigating the neurobiology of consciousness is to experimentally manipulate consciousness as a variable and then visualize the resultant functional brain changes with advanced imaging techniques. To begin investigation into this area, healthy volunteers underwent positron emission tomography scanning while listening to randomized word lists in both conscious and unconscious conditions. Following anaesthesia, subjects had no explicit memories. Nonetheless, subjects demonstrated implicit memory on a forced-choice test . These subsequent memory scores were correlated with regional brain metabolism measured (...) during encoding. Conscious recall and unconscious recognition memory demonstrated considerable anatomic overlap in correlating significantly with relative glucose metabolism in auditory verbal memory areas. However, only conscious recall correlated with mediodorsal thalamic nucleus activity; unconscious recognition memory did not. These findings suggest that conscious versus unconscious memory distinctions may depend on the presence or absence of correlated thalamic activity, and directly implicate the thalamus in the neurobiology of consciousness.

There is a perplexing transition in Dr. Reza Davari's thought, when he problematizes the relation between Iranian and Western history/cultures, on which this paper is focusing. The interperative objective is to clarify this transition on the basis of the implicit relation between the two most fundamental concepts in his earlier and later thought respectively westernization and underdevelopment. Although, by this transition, the level of discussion transits from an ontologico-philosophical to an intellectualist one. So, there are two different levels of problematization (...) in his thought which differ deeply. Therefore, we are not just dealing with the substitution of fundamental concepts, but with different problematizations and different levels of discussion. Obviously, there will be new problems arising which are not just concerning with the justification of the transition but with the problematization of westernization itself. Finally, it's been concluded that in order to clarify these new problems, we should step back to the level of philosophical discussion, and first of all to the clarification of the I-not-I relation which has been neglected thoroughly in the whole project.

Descartes' methodical doubt is being criticized by naïve realists and others who don't find doubt as a good starting point for metaphysical thought, however, the philosophical achievements of his method have been absorbed in all later philosophies. The objective of this paper is to demonstrate how an inevitable question concerning the foundation of Descartes' mathesis universalis, which led him to investigate this foundation by applying this very method in Metaphysics, has finally enabled him to discover his most important philosophical principle, (...) i.e., the necessary relation between being and reason in the identity of the "I". To demonstrate this, after summarizing the fundamental ideas of mathesis uneversalis, and showing the inner necessity of introducing the methodical doubt to fortify these ideas, the decisive role of metaphysical doubt as the third step of the methodical doubt, and malicious demon as its second phase would be highighted. It would also become clear that the metaphysical doubt has a great importance as a turning point from different aspects: as a knot that ties mathesis universalis with its underlying Metaphysics; as a bridge from within the psychological "I" to the metaphysical "I".

Abstract -/- The objective of this paper is to clarify that the distinction Malkam Khan makes between natural (ordinary) and scientific reason, is crucial to his entire thought, and he makes this distinction because he is aware of the critical status the idea of method has in the formation of the scientific reason. So, I try to prove that the idea of method and the distinction he makes between these two reasons are the same idea which is to be considered (...) as his central idea. According to Malkam Khān, following the principles of this reason is the key to prosperity and progress. So, he believes that in order not to be colonized, we should progress, and in order to become prosperous, we should act according to the principles of scientific reason. On the basis of this analysis I claim that he thinks like a strategist, therefore, whenever we want to interpret his thought as a consistent whole, we should consider this particular approach. My own approach in this paper is in harmony with the main argument of Malkam Khān, trying to interpret his thought not on the basis of his personal character, his concealed intentions, or simple political events in which he was a part, but on the basis of seeing his thought as scientifically (objectively) as possible by focusing on his own writings in different stages of his thought-life, and analyzing them structurally.

The purpose of this qualitative study was to analyse nurses’ professional dignity in their everyday working lives. We explored the factors that affect nursing professional dignity in practice that emerge in relationships with health professionals, among clinical nurses working in hospitals and in community settings in central Italy. The main themes identified were: (i) nursing professional dignity perceived as an achievement; (ii) recognition of dignity beyond professional roles. These two concepts are interconnected. This study provides insights into professional dignity in (...) nursing being perceived as an achievement linked to the intrinsic dignity of every human being. The ‘nursing professional dignity perceived as an achievement’ was perceived as having declined in different social factors. Some factors of nursing professional dignity perceived as an achievement were attained more easily in community settings. ‘Recognition of dignity beyond professional roles’ underpins the intrinsic dignity as an expression of humanity, embedded in persons regardless of any profession, and values, such as: respect, moral integrity, humility, working conscientiously and kindness.

Ontological and methodological constraints on a theory of cognition that would generalize across species are identified. Within these constraints, ecological arguments for animal-environment mutuality and reciprocity and the necessary specificity of structured energy distributions to environmental facts are developed as counterpoints to the classical doctrines of animal-environment dualism and intractable nonspecificity. Implications of and for a cognitive theory consistent with Gibson's programme of ecological psychology are identified and contrasted with contemporary cognitivism.

What if human joy went on endlessly? Suppose, for example, that each human generation were followed by another, or that the Western religions are right when they teach that each human being lives eternally after death. If any such possibility is true in the actual world, then an agent might sometimes be so situated that more than one course of action would produce an infinite amount of utility. Deciding whether to have a child born this year rather than next is (...) a situation wherein an agent may face several alternatives whose effects could well ramify endlessly on such suppositions, for the child born this year would be a different person—one who preferred different things, performed different actions, and had different descendants—from a child born next year. It has recently been suggested that traditional utilitarianism stumbles on such cases of infinite utility. Specifically, utilitarianism seems to require, for its application, that all experience of pleasure and pain cease at some time in the future or asymptotically approach zero.2 If neither of these conditions holds, then the utility produced by each of two alternative actions may turn out to be infinite, and utilitarianism thus loses its ability to discriminate morally between them.

This essay explores the claim that bioethics has become a mode of biopolitics. It seeks to illuminate one of the myriad of ways that bioethics joins other institutionalized discursive practices in the task of producing, organizing, and managing the bodies—of policing and controlling populations—in order to empower larger institutional agents. The focus of this analysis is the contemporary practice of transnational biomedical research. The analysis is catalyzed by the enormous transformation in the political economy of transnational research that has occurred (...) over the past three decades and the accompanying increase in the numbers of human bodies now subjected to research. This essay uses the work of Michel Foucault, particularly his notion of docile bodies, to analyze these changes. Two loci from the bioethics literature are explored—one treating research in the United States and one treating research in developing countries. In the latter, we see a novel dynamic of the new biopolitics: the ways in which bioethics helps to create docile political bodies that will police themselves and who will, in turn, facilitate the production of docile human bodies for research.

Within the moral/social order maintained and reproduced by biomedical ethics (i.e., the “peaceable community”), suffering is a senseless accident with no value. Insofar as suffering compromises the fundamental pillar of this order, namely, autonomy, it threatens the existence of the “peaceable community”. Consequently, biomedical ethics is only able to offer those who suffer one moral or practical response: that of elimination, embodied most vividly in the increasingly approved practice of assisted-suicide. Another moral/ social order, however, the “peaceable Kingdom” or the (...) “Body of Christ”, provides an alternative understanding of the meaning, purpose, and significance of suffering, through the Roman Catholic sacrament of anointing of the sick. Recognizing the power of sickness and suffering to “dis-inscribe” bodies of their normative self-understandings, the Church responds with a set of liturgical practices which intend to respond to the dynamics of suffering, re-inscribe these bodies, and assist persons in fulfilling the vocation of “participating in Christ's suffering for the salvation of the world”.

There is already a copious literature comparing Claudius' oration on the admission of the primores Galliae into the Roman Senate with Tacitus’ account of the speech and of the opposition's case in Annals 11. 23–4. Yet the Emperor's own purpose in speaking as he did still needs some illumination. Scholarly concentration on technical points about the citizenship, on Claudius’ antiquarianism and on his debt to Livy has been fruitful, but it has often distracted attention from Claudius’ immediate aim. Meanwhile, Tacitus’ (...) interpretation has been insidious in colouring our view of what course of action the imperial orator was trying to defend before the Senate. (shrink)

In an influential essay entitled Why abortion is wrong, Donald Marquis argues that killing actual persons is wrong because it unjustly deprives victims of their future; that the fetus has a future similar in morally relevant respects to the future lost by competent adult homicide victims, and that, as consequence, abortion is justifiable only in the same circumstances in which killing competent adult human beings is justifiable.1 The metaphysical claim implicit in the first premise, that actual persons have a future (...) of value, is ambiguous. The Future Like Ours argument (FLO) would be valid if “future of value” were used consistently to mean either “potential future of value” or “self-represented future of value”, and FLO would be sound if one or the other interpretation supported both the moral claim and the metaphysical claim, but if, as I argue, any interpretation which makes the argument valid renders it unsound, then FLO must be rejected. Its apparent strength derives from equivocation on the concept of “a future of value”. (shrink)

Several commentators have noted that “justice has not fared well in the revival of virtue ethics”; it “has become damagingly marginalized” and “no longer has a starring role.” Given its traditional place among the four cardinal virtues this is a remarkable state of affairs and yet exactly this has occurred has not been adequately explored or explained. In this paper, I argue that the particular moral virtue of justice has been largely disregarded by the contemporary virtue theorists primarily because their (...) conception of justice is so different from Aristotle’s. Accordingly, they do not need the virtue of justice to do the kind of explanatory work in their systems that it does in Aristotle’s. (shrink)

It is claimed by the future like ours anti-abortion argument that since killing adult humans is wrong because it deprives them of a future of value and the fetus has a future of value, killing fetuses is wrong in the same way that killing adult human beings is wrong. In The morality of abortion and the deprivation of futures (this journal, April 2000) I argued that the persuasive power of this argument rests upon an equivocation on the term “future of (...) value”. If the expression means “a potential future of value” then the moral claim is implausible because people do not in general have rights to what they need to fulfill their potential; if the expression means “self-represented future of value” then the argument fails because the fetus does not represent its future. Under no interpretation is the argument sound. In Deprivations, futures and the wrongness of killing (this journal, December 2001) Donald Marquis, author of the future like ours argument, responds at length to this objection. In the present essay the focus of the debate shifts to the proper interpretation of the right not to be killed. Donald Marquis argues that this liberty right entails the welfare right to the means necessary to sustain life; I argue that the right not to be killed does not entail unlimited welfare rights. On Marquis's view, the right not to be killed confers upon the fetus the right to whatever it takes to sustain life; on the view I defend, the right not to be killed does not confer upon the fetus or anyone else the right to another person's body. On Marquis's view, abortion is almost never permissible; on my view abortion is almost always permissible. (shrink)
